r sa'rns ADJUSTABLE DOUBLE-BURNER TOOL-HEATER.

Application filed March 27, 1915.

T0 aZZ whom it may concern Be it known that I, ALVADER D. HORNE,residing at Haverhill, in the county ofEssex and State of Massachusetts,have invented certain new and useful Improvements in AdjustableDouble-Burner Tool-Heaters, of which the following is a specification.

In the art of manufacturing shoes, edge setting machines have come intouse which are provided with reversible burnishing irons consisting of ashank and two diverging irons, one for setting the sole edge and theother usually for the heel setting operation. In order to keep the ironin use at the proper temperature, a gas flame burner is usuallyprovidedto direct a flame on the back of the tool thatis being used, the othertool beingout of the range of the heating flame when not in use. Thismanner of heating the tool is objectionable in that when it is necessaryto turn the tool around to bring the other iron into operative position,

much time is lostbefore the other iron is heated up to its properburnishing temperature.

It-is therefore theprincipal object of my present invention to provide aburner that will give a double-flame, one flame of which beingconstantly directed against the tool that is to the front and in use,while the:

other flame may be kept directed against the rear or idle tool tomaintainitat the de-- sired temperature so that it can be instantly usedwhen brought into operative position,

means being provided whereby the flames can be relatively adjusted orregulated to give the same degree of heat or different degrees of heatas may be required to maintain a definite even temperature in bothtools, while the edge setting operations are being performed.

The invention therefore resides in those novel features of construction,combination and arrangement, all of which will be first fully described,then be specifically-pointed out in the appended claims, reference beinghad to the accompanying drawing, in which Figure 1 is a perspective viewof a part of an edge setting machine embodying the invention. Fig. 2 isa detail elevation view of the burner attachment, per 86. Fig. 3 is across section on the line 3-3 of Fig. 4;. Fig.

Specification of Letters Patent.

Patented July 27, 1915.

Serial No. 17,357. ing, in which like numerals of reference designatelike parts in all of the figures, 1 represents the edge setting machine,which may be of any approved type or construction as,

for instance, the Rossmoyer edge setting machine, as it is known in thetrade, and this machine includes the support 2 for the burnishing toolin which the shank 3 of the tool is reversibly mounted, the head 4 ofthe tool having the diverging burnishing tools proper 5 and 6 attachedthereto in the usual manner. I I i I 7 is the usual rest and 8 is theusual gas supply pipe that delivers into a T 9 from which the lateralbranches to each side of the machine (when the machine is a double one)are extended. Each lateral branch includes a cutoff valve 10, and acoupling 11 by means of which the burner proper is secured to thelateral pipe. 2 r

The burner proper, which constitutes the essential part of presentinvention, consists of a pipe 12 that is coupled at 11 tothe lateralpipe and delivers into a valve 13 to register with the through port 14,the latter also registering with the outlet burner pipe 15 that issecured in the valve shell or cas-- ing 13 and extends to a position inproximity to the front burnishing-tool so that its discharge end '16will direct a flame against the rear of the front tool, be it 5 or 6,ac-

cordingly as to which 'ofthe tools '5 or 6 is in use. p i

The valve 13, it Willbe noticed, has a vertical duct 18-23 that mergeswith the cock ing, soldering or any other well known man' ner. Theauxiliary pipe 24. extends forwardly and'has'its front end turned back,as at 25 to direct a flame on the back face of the rear or idleburnishing tool. The cook 19 has an elongated recess 20 to cooperatewith the stop 21 whereby the turning movement of the cook 19 may belimited to OE and on positions. 7

In the practical use of my invention, it will be observed, that flamesmay be kept directed on both the active and the inactive tool, or cutoff from the inactive tool, and

the relative heating intensity of the two I can turn ofl the auxiliaryburner section and save thatmuch gas.

In the art as heretofore practised with the single burner, thedifficulty is that both ironscould not be kept at the proper heat; oneiron would get too cold, while the other would get too hot. This troubleis overcome by the use of my invention and the operator is thereforeenabled to do more work and better work in less time, because he canadjust the burner to heat each iron correctly and keep the irons attheproper'temp'erature while working with the machine. Again,

' with the old style single flame burner, the

operator must handle his work twice in order to accomplish good results,whereas with the use of my invention he can burnish the forepart of theedge and the shank while he has the shoe in his hands, thus handling hisIvpjrkbut once and thereby saving time and a or.

From the foregoing taken in connection the gas from said inlet pipetos'aid main with theaccompanying drawing, it is thought the completeconstructiomoperation and advantages of my invention will be readilyunderstood by those skilled in the art to which it relates. I

What I claim is: t

1. The combination with the rotatable tool head of an edge burnishingmachine and the pair of burnishing tools divergingly prowith said gassupply pipe, a control cock and a main burner discharge pipe fordirecting a flame against the front or operative one of the tools, andan auxiliary burner pipe connected with said control cock and arrangedwith its discharge orifice to direct a flame against the other orinactive tool, said control cock having provisions for shutting Off andregulating the flow of gas through said auxiliary burner pipesubstantially as shown 7 and for the purposes described.

3. As a new article of manufacture, a-

heating burner attaolnnent for edge setting machines comprising a cock,a main burner pipe extending from said cock, an auxiliary burner pipeextending from said cock, and

an inlet pipe extending from said cock and adapted to be attached to asource of gas supply, said cock having ducts for conveying and auxiliaryburner pipes, said cock having provision for controlling the flow ofgas-to one of said burner pipes, all being arranged fsubstantially asshown and for the purposes described.
